You have to muck about in /proc/asound a bit.

For example, assuming you know that card 1 has MIDI devices associated 
with it, you could use "head -n1 /proc/asound/card1/midi0" to get the name 
of the first MIDI device, then cross-reference with 
/proc/asound/seq/clients (or the output from aconnect).

It's something of a PITA, but it's better than a stab in the dark, which 
is what you're doing now.  You can't know with absolute certainty that 
hw:1 will be a MIDI device, much less the one you want.  Though it 
probably will be.

Don't even get me started on duplicate names, especially where USB is 
involved.  A lot of manufacturers, and I just noticed that Yamaha is one 
of them, don't give you enough information to differentiate among devices.
